How do we determine what something cost? If I bought a bunch of gear in an estate/garage sale and sold enough of it to get back my investment, is what I have left over considered free? Or, should I prorate the purchase price and if so how do I do that?
As to the speaker size question, maybe the system should need to fit in a certain size box, like the airlines do with carry on bags...........
